Answer:
= 127.06 kPa
Explanation:
According to pressure law which states that the pressure of a fixed mass of a gas is directly proportional to its absolute temperature at constant volume.
Therefore;
P1/T1 = P2/T2
P1 = 123 kPa
T1 = 30°C + 273°C = 303 K
T2= 40°C + 273°C = 313 K
Therefore;
P2 = P1T2/T1
= (123 × 313)/303
= 127.06 kPa
